Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 375: Pulse Or Digital Communications

This is the generic class for pulse or digital communication systems using electrical or electromagnetic signals. Such communication includes transmitting an intelligence bearing signal from one point to another in the form of discrete variations in some parameter of the electrical or electromagnetic signal.

Subclass 240.16: Motion vector
Subclass E7.193: Filtering (EPO)
Subclass E7.253: Involving temporal subsampling, e.g., frame decimation (EPO)

Class 348: Television

Generating, processing, transmitting or transiently displaying a sequence of images, either locally or remotely, in which the local light variations composing the images may change with time.

Subclass 699: Motion vector generation

Class 360: Dynamic Magnetic Information Storage Or Retrieval

This class is an integral part of Class 369, Dynamic Information Storage or Retrieval, and is the specific class for apparatus and corresponding processes for the storage and retrieval of information based on relative movement between a magnetic record carrier and a transducer. It includes apparatus and corresponding processes for making copies or editing of records falling within the above definition. A magnetic record carrier within the meaning of this class is an element which consists of a magnetizable material or is comprised of a coating or impregnation of magnetizable material which is intended for the storage of more than a single bit of information.

Subclass 77.04: By memory storage of repeatable error or correction
Subclass 78.04: For rotary carrier (e.g., disc)
Subclass 78.06: Specified velocity pattern during access
Subclass 78.07: Controlled by memory device

Class 318: Electricity: Motive Power Systems

This is the generic class for system of electrical supply and/or of control for one or more electric motors where the electric motor is claimed in combination with such systems of supply and/or control and the electric motor as claimed constitutes the ultimate and sole electrical load device supplied by the system or constitutes the ultimate and sole electrical device being controlled.

Subclass 561: Adaptive or optimizing systems including bang-bang servos

Class 700: Data Processing: Generic Control Systems Or Specific Applications

This class is structured into two main divisions: (1)for the combination of a data processing or calculating computer apparatus (or corresponding methods for performing data processing or calculating operations) AND a device or apparatus controlled thereby, the entirety hereinafter referred to as a "control system". (2)for data processing or calculating computer apparatus (or corresponding methods for performing data processing or calculating operations) wherein the data processing or calculating computer apparatus is designed for or utilized in a particular art device, system, process, or environment, or is utilized for the solution of a particular problem in a field other than mathematics (arithmetic processing per se is classified elsewhere).

Subclass 69: Positional (e.g., velocity, acceleration)

Class 706: Data Processing:Artificial Intelligence

This is a generic class for artificial intelligence type computers and digital data processing systems and corresponding data processing methods and products for emulation of intelligence (i.e., knowledge based systems, reasoning systems, and knowledge acquisition systems); and including systems for reasoning with uncertainty (e.g., fuzzy logic systems), adaptive systems, machine learning systems, and artificial neural networks.

Subclass 52: Reasoning under uncertainty (e.g., fuzzy logic)

Class G9B/21.015:

Class G9B/7.047:

Class 327: Miscellaneous Active Electrical Nonlinear Devices, Circuits, And Systems

This is the residual class for electrical devices, circuits or systems having an output not directly proportional to its input and comprising at least one component which can provide gain or can route electrical current and which device, circuit or system does not form a complete system such as is classified specifically elsewhere or a subcombination of utility only in such elsewhere classified system.

Subclass 142: Reset (e.g., initializing, starting, stopping, etc.)
Subclass 143: Responsive to power supply
Subclass 198: Initializing, resetting, or protecting a steady state condition

Class 386: Television Signal Processing For Dynamic Recording Or Reproducing

Apparatus and corresponding processes for processing a sequence of images, in which the light variation composing the images may change with time for dynamic recording or reproducing of the sequence of images. The processing involves the following steps: (a) Receiving a sequence of images from a local (e.g., camera, etc.) or remote source (e.g. broadcasting station, satellite, cable, etc.); (b) Converting the received sequence of images into a form suitable for dynamic storage, which form may or may not be reproduced later; or (c) Converting retrieved information from a dynamic storage medium into a sequence of images.

Subclass 111: Intraframe or interframe
Subclass 114: Noise reduction
Subclass 125: Using disc
Subclass 126: Optical
Subclass 70: Disc
Subclass E9.013: Involving data reduction (EPO)

Class G9B/27.019:

Class G9B/27.033:

Class 369: Dynamic Information Storage Or Retrieval

Apparatus for the storage or retrieval of arbitrarily variable information which is retained in a storage medium by variation of a physical characteristic. The information is stored or retrieved by causing or sensing a variation of a physical characteristic of the storage medium by a transducer having relative motion along a continuous path.

Subclass 44.22: Lens or mirror floats, (e.g., magnetic field support or lens/mirror can freely float and pivot about its own axis, etc.)
Subclass 44.28: While track jumping or crossing
